Ring crush test
In this test, the sample is prepared according to the standard dimensions and is placed in the attachment related to the test, which is a cylinder with a groove in the center, in a circle. Part of the width of the sample is outside the attachment.
This set is pressed between two pressure plates in a suitable device. The amount of resistance against crushing of this sample is investigated.
Sample dimensions:152 x 127 mm
Relevant standard:
1. ISIRI 1411, ASTM D 1164
To prepare the sample, the device shown above is used with the cutting blade GT-6018-A.
Carton edges resistance test:
In this test, the desired sample, which is prepared according to the standard dimensions, is placed vertically (from the edges) in its appropriate test attachment. This set is pressed between two compression plates.
The amount of resistance against crushing of this sample is investigated.
The sample should be cut into a rectangle. Model GT-6019-A preparation device made by Gotech Taiwan
The sample is cut in the form of two connected trapezoids. Model GT-6019-B preparation machine made by Gotech Taiwan.
The dimensions of the cut samples are as follows:
The samples prepared by the above devices are placed under pressure in the corresponding attachment between two pressure plates.
The level of resistance against crushing of these edges is examined.
The related attachment is model GT-6011-2 made by Gotech Taiwan.
- Adhesion resistance test of cardboard layers:
In this test, the interlayer resistance of the cardboard is examined.
The attachment related to this test is inserted between the cardboard layers and these layers are separated from each other by applying pressure with the appropriate device.
The level of interlayer adhesion is examined in this test.
